Current and voltage excitations for the Eddy current model

by R. Hiptmair and O. Sterz

(Report number 2003-07)

Abstract
We present a systematic study of how to take into account external excitation in the Eddy current model. Emphasis is put on mathematically sound variational formulations and on lumped parameter excitation through prescribed currents and voltages. We distinguish between local excitation at known contacts, known generator current distributions and non-local variants that rely on topological concepts. The latter case entails the violation of Faraday's law at so-called cuts and prevents us from reconstructing a meaningful electric field.
